Re: large MLCC capacitors for coupling audio
|
I am using these:?
I am trying to get away from Electrolytics. Experimenting, seeing what is new or changed. The caps are microphonic but hey, they are going in a? microphone. You have to physically?tap them to get any kind of response. I am using them in my hydrophone board and they work well and I have had no issues.
One may note the part above is rated for 35V. With P48 they see about 22V across them.?

I know you're working on all-SMT versions of your OPA designs, but why not use SMT elcaps with enlarged solderpads, so you can solder them by wetting the pad that extends outside of the elcap pins? Cheaper, no (or less) microphonics, higher capacities available for improved CMRR and lower low-end noise, audio-grade versions available if that means anything to you, no cracking issues... Maybe I'm missing something, but could you explain your rationale for using MLCCs?
Btw, did you check your builds for microphonics?
